H5se12 is a side scan sonar with echo sounder ( ES)


The H5se12 is the Hydra™  ultra-compact ultra-high resolution side scan sonar with an integrated survey echo sounder ( ES) of the Hydra™ series. The ultra-compact ultra-high-resolution side scan sonar (SSS) of the Hydra™ series is combined with a survey echo sounder (ES). It can be installed on board of any vessel, including autonomous vehicles. It is applied for search of the sunken objects, monitoring of objects of underwater infrastructure, checking of a condition of fairways and port waters, measuring works with depths up to 10 m for SS or up to 30m for ES.  Small-sized low-profile design allows you to place the sonar on Board of the ship on the rod  of d=30 mm and with minimal immersion.  
Small-sized narrow-profile design allows you to place sonar on board of any vessel on a rod of  d=30mm with minimal immersion.
It is possible to install on remote controlled autonomous vehicles (AUSV, AHSV).

Ultra-high range resolution (0,5 cm) for object search and target detection. SSS provides real - time high-quality bottom image with photographic quality in a swath of up to 78m , using a frequency of 1200 kHz.
The ES can operate simultaneously with the SSS and allows to make the measurements at depths up to 50 m. The usage of SSS while measuring allows application of measurement technology with instrumental evaluation, to avoid artifacts between tack distances (skipping objects) in the normal survey echo sounding .
When using the additional  all-round view option, it is possible to operate in the all-round sonar mode from the ice surface or while the vessel is stationary.
